In 1935, when Chinese intelligence agent Mei Ying, who posed as Marshal Kai Ti Chang's secretary, revealed her true allegiance, the Feng Twins were the ones who witnessed it and reported back to their master.

While Mei Mei was reluctant to fight Jones on the grounds that "he looks like fun", she was convinced her sister to put business before pleasure. Jones too was reluctant to physically attack the women, but soon realized that it would be a fight for his life.

Despite their advanced skills, the Feng Twins were defeated by Jones. When he moved to release Mei Ying, however, a trap door opened beneath the archaeologist and he fell into the Temple of Kong Tien.
